Chemical Bonding Review

Front

How do covalent bonds form?

Back

Covalent bonds form by sharing valence electrons between atoms.

What is the name of the compound produced when magnesium burns in oxygen?

Back

Magnesium oxide (MgO).

Front

What type of ion is an anion?

Back

An anion is a negative ion.

Front

Why do all bonds form?

Back

Bonds form to fill the outermost energy level of atoms.

How many electrons do nitrogen atoms share in a nitrogen molecule (N2) with a triple bond?

Back

6 electrons.

Front

What is a covalent bond?

Back

A covalent bond is a chemical bond formed by the sharing of electron pairs between atoms.

Front

What is an ionic bond?

Back

An ionic bond is a chemical bond formed through the transfer of electrons from one atom to another, resulting in the formation of charged ions.

Front

What is the octet rule?

Back

The octet rule states that atoms tend to form bonds in such a way that they have eight electrons in their valence shell, achieving a stable electron configuration.

Front

What is a molecule?

Back

A molecule is a group of two or more atoms bonded together by covalent bonds.

Front

What is the difference between a polar and nonpolar covalent bond?

Back

A polar covalent bond has unequal sharing of electrons, resulting in partial charges, while a nonpolar covalent bond has equal sharing of electrons.
